its left-hand side to a number of expressions passed in the argument list and returns true if a match is found. NOT IN always returns the opposite of IN. Some examples of its use are: select RoomNo etc., until a match is found, in which case the corresponding result is returned. If there is no match and there is an ELSE clause, is returned. If there is no match and no ELSE clause important to know that the comparisons are done with the ‘=’ operator, so a null will not match a null . If is NULL, the only way to get a non-NULL result is via the ELSE clause
